Description

Technical Field

[0001] This application relates to the field of testing technology for cooling oils, and in particular to a corrosion deposition support system for charged conductors at high temperatures. Background Technology

[0002] Oil coolers are a common type of oil cooling device used in hydraulic and lubrication systems. This device enables heat exchange between two fluid media with a certain temperature difference, thereby reducing oil temperature and ensuring normal system operation. Currently, oil cooling systems are widely used in electronic products such as new energy vehicles, low-altitude power systems, large hybrid oil-cooled motors, energy storage systems, and large servers. To ensure the efficient operation and long-term stability of industrial equipment cooling systems, the performance of the cooling oil is usually tested.

[0003] In recent years, with the rise of new energy vehicles, low-altitude transportation, and other industries, the demand for high-power motors has been increasing year by year, making the development and testing of matching motor cooling oils increasingly important. Currently, there is no system, either domestically or internationally, for testing the corrosion and deposition of copper wires under energized conditions, making the testing of motor oils cumbersome and complex, greatly increasing the product development cycle and the time and cost of bench testing.

[0004] Therefore, there is an urgent need in this field for a system that can perform corrosion and deposition tests on copper wires under energized conditions, in order to reduce product development cycles and bench testing time and costs. Utility Model Content

[0006] The corrosion deposition support system for charged conductors at high temperatures provided in this application adopts the following technical solution:

[0007] A high-temperature corrosion deposition support system for charged conductors includes a top fixing and connection mechanism, a sample fixing and testing mechanism, and a temperature control and testing mechanism. The top fixing and connection mechanism includes a fixing plate and an external connecting plate. A high-temperature sample is placed in a glass container, which is detachably mounted at the bottom of the fixing plate. An external pumping system facilitates the flow between the sample's gas and liquid spaces. The external connecting plate is located at the top of the fixing plate for connecting an external suspension device. The sample fixing and testing mechanism is located at the bottom of the fixing plate and extends into the glass container to provide sample fixing and connection to the testing system. The temperature control and testing mechanism is located at the bottom of the fixing plate and extends into the glass container to collect and control the temperature during testing.

[0008] Preferably, the bottom wall of the fixing plate is provided with an annular mounting groove for mounting the glass container, and the sample fixing and testing mechanism and the temperature control and testing mechanism are all located within the inner circle of the mounting groove.

[0009] Furthermore, the sample fixing and testing mechanism includes a mechanism support one and a mechanism support two. The mechanism support one is provided with four side supports, including side support one, side support two, side support three and side support four arranged sequentially from top to bottom.

The top of the mechanism support two is provided with a lead wire hole two. The mechanism support two is inserted into the fixing plate and the lead wire hole two extends out of the fixing plate.

[0010] Furthermore, the side supports arranged opposite each other on the first and second mechanism supports form a test circuit in pairs. Side support one and side support five form a test circuit, and the test sample is fixed by welding or pressing. Side support two and side support six form a test circuit, side support three and side support seven form a test circuit, and side support four and side support eight form a test circuit. The two circuits closer to the fixed plate are gas test circuits, and the two circuits farther from the fixed plate are liquid test circuits.

[0011] Furthermore, the mounting groove is an annular groove, and the two sets of sample fixing and testing mechanisms are evenly spaced around the circumference of the mounting groove.

[0012] Preferably, the temperature control and testing mechanism includes a support bracket three, with a temperature control lead hole at the top. Side supports nine and ten are sequentially arranged from top to bottom on the sidewalls of the support bracket three. The support bracket three is embedded in the bottom of the fixing plate via a slot. The temperature control lead hole extends out of the fixing plate. Side supports nine and ten are arranged inwards, with side support nine located at the center of side supports one and two, and side support ten located at the center of side supports three and four. Side support nine is used to measure and control gas temperature, and side support ten is used to control liquid temperature.

[0013] Preferably, the structural components of the top fixing connection mechanism, sample fixing and testing mechanism, and temperature control and testing mechanism include, but are not limited to, structures made of polytetrafluoroethylene or PEEK material.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains. The use of terms such as "a" or "an" in this patent application specification and claims does not indicate a limitation of quantity, but rather indicates the presence of at least one.

[0021] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0022] This application discloses a corrosion deposition support system for charged conductors at high temperatures.

[0023] Reference Figure 1 and Figure 2 A corrosion deposition support system for charged conductors at high temperatures includes a top fixing and connection mechanism 1, a sample fixing and testing mechanism 2, and a temperature control and testing mechanism 3. The top fixing and connection mechanism 1 is used to connect and fix the sample fixing and testing mechanism 2, the temperature control and testing mechanism 3, and the host system. The structural components of the top fixing and connection mechanism 1, the sample fixing and testing mechanism 2, and the temperature control and testing mechanism 3 include, but are not limited to, structures made of polytetrafluoroethylene or PEEK.

[0024] Reference Figure 1 and Figure 2 The top fixed connection mechanism 1 includes a fixed plate 11 and an external connection plate 12. The high-temperature sample is placed in a glass container (not shown in the figure). The glass container includes, but is not limited to, a high borosilicate beaker. The glass container is embedded in the bottom of the fixed plate 11. The flow between the sample gas and liquid spaces is realized through an external pumping system. The external connection plate 12 is bonded and fixed to the top of the fixed plate 11 for connecting an external suspension device. The external suspension mechanism includes, but is not limited to, a high-precision robotic arm mechanism, which controls the assembly of the support system and the host system. This can greatly improve the operating accuracy of the system, reduce the risk of high-temperature sample gas leakage, meet the requirements of the EHS management system, and be environmentally friendly.

[0025] Furthermore, an annular mounting groove 111 for mounting glass containers is provided on the bottom wall of the fixing plate 11. The sample fixing and testing mechanism 2 and the temperature control and testing mechanism 3 are both located within the inner circle of the mounting groove 111. In feasible embodiments, the mounting groove 111 can be a groove of any shape. In this embodiment, the mounting groove 111 is preferably an annular groove.

[0026] Furthermore, the external pumping system (not shown in the figure) employs a corrosion-resistant and high-temperature-resistant magnetic pump. Pumping time and intervals can be set according to operating conditions, and a data acquisition system is used for precise control and testing. This pumping system consists of an inlet pipe, an outlet pipe, a pump body system, and a control system. The materials used in contact with the pump pipe and pump body are corrosion-resistant and high-temperature-resistant, which is existing technology and will not be elaborated upon further.

[0027] Reference Figure 1 and Figure 2 The sample fixing and testing mechanism 2 has two sets of components that are evenly spaced around the circumference of the mounting groove 111 and extend into the glass container. These components are used to fix the sample and connect the testing system. The power supply and data acquisition testing unit uses this mechanism. The temperature control and testing mechanism 3 has one set that is installed at the bottom of the mounting plate 11 and extends into the glass container. This mechanism is used to acquire and control the temperature during the testing process and to fix a high-precision temperature sensor on the top mechanism.

[0028] Furthermore, the sample fixing and testing mechanism 2 includes a mechanism support 1 21 and a mechanism support 22. The mechanism support 1 21 has four side supports integrally formed, including side support 1 211, side support 212, side support 3 213 and side support 4 214 arranged sequentially from top to bottom. The top of the mechanism support 1 21 is provided with a lead wire hole 1 23. The mechanism support 1 21 is fixed to the fixing plate 11 by a slot and a top fastening screw, and the lead wire hole 1 23 extends out of the fixing plate 11. The mechanism support 2 22 has four side supports integrally formed, including side support 5 221, side support 6 222, side support 7 223 and side support 8 224 arranged corresponding to side support 1 211, side support 212, side support 3 213 and side support 4 214 on the mechanism support 1 21. The top of the mechanism support 2 22 is provided with a lead wire hole 2 24. The mechanism support 2 21 is fixed to the fixing plate 11 by a slot and a top fastening screw, and the lead wire hole 2 24 extends out of the fixing plate 11.

[0029] The side supports on the first support 21 and the second support 22 are arranged in pairs to form a test circuit. Side support 1 211 and side support 5 221 form one test circuit. The test sample is fixed by welding or pressing. Side support 2 212 and side support 6 222 form one test circuit. Side support 3 213 and side support 7 223 form one test circuit. Side support 4 214 and side support 8 224 form one test circuit. The two circuits closer to the fixed plate 11 are gas test circuits, and the two circuits farther away from the fixed plate 11 are liquid test circuits. The test leads of the first support 21 and the second support 22 are connected to the acquisition and test circuits through lead hole 1 23 and lead hole 2 24.

[0030] Furthermore, the temperature control and testing mechanism 3 includes a mechanism support 31. The top of the mechanism support 31 is provided with a temperature control lead hole 32. The side wall of the mechanism support 31 is integrally formed with side support 9 33 and side support 10 34 from top to bottom. The mechanism support 31 is embedded in the bottom of the fixing plate 11 through a slot. The temperature control lead hole 32 passes through the fixing plate 11. The side support 9 33 and side support 10 34 are set inward. The side support 9 33 is located at the center of side support 1 211 and side support 2 212. The side support 10 34 is located at the center of side support 3 213 and side support 4 214. The side support 9 33 is used to measure and control the gas temperature, and the side support 10 34 is used to control the liquid temperature.

[0031] This invention relates to a high-temperature corrosion deposition support system for charged conductors, featuring a rapid nested design that requires no training and allows for quick assembly and testing. Considering the extended experimental time, except for the temperature control, fixing mechanisms, and pumping system, the rest is designed for single use, avoiding the influence of uncertainties caused by connection and data acquisition on the measurement results. The system's sample testing comprises four independent testing units, capable of simultaneously performing two sets of high-temperature liquid tests and two sets of high-temperature gas tests, significantly improving testing efficiency.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
